I have a ton of questions, so everyone bear with me.
1) Its currently 9.1c in my highland terrarium (!). Recently it has only been getting down to 14-15c with two frozen water bottles, so I included all of them, instead of the usual cycling. Is this too cold? My higland growlist is at the bottom of this post.
2) Are my lowlanders desperately in need of repotting? Most of them are in the 2.5" PFT pots, except for my truncata, and one of my ampullaria. My rafflesianias have leaves about 4-5", and my ampullaria have about 6" leaves. My ventrata has 8" leaves, and is in a 3" pot.
3) Is is true that highlanders have smaller root systems? I, of course, don't want to dig them out and investigate, and put them in shock. My highland plants are a little smaller (diameter-wise), so I don't think they need to be repotted, but I could be wrong. Pictures available if needed.
4) Is it ok if my lowland terrarium drops to say 20c at night? Humidity is maintained in both aqariums at no less than 70%.
